“From the title, one might expect Lee Smolin to be some cranky science writer, or even some sort of anti-science Luddite. However, Smolin is the real deal. He got his doctorate in physics at Harvard, spent some time teaching at Yale, spent more time studying at the Princeton Institute for Advanced Study (the place Einstein spent his last twenty years), is one of the founders of a model called “loop quantum gravity,” and he has worked on string theory. Folks in the physics community should give him a listen, and more broadly people interested in science will likely find this an interesting book.”
